Whatever deficits Bill Shorten may be accused of having as the alternative prime minister, ahead of next year's federal election, they are more than compensated by the professionalism and discipline of the Labor machine around him.

The Opposition Leader is interrupted by protesters before promising an overhaul of superannuation and environmental laws if Labor wins office, along with a multi-billion-dollar housing-affordability plan, in a speech to the party's national conference.

Opening the ALP national conference in Adelaide, Mr Shorten will seek to counter the Coalition's attacks on his negative gearing policy, declaring Labor "the party of home ownership" and "the party of affordable housing".

LNP President Gary Spence says Queensland's new law banning political donations from property developers has forced him to resign from his role with the party, with legal advice suggesting he could face possible jail time due to his background in urban development.

"It shouldn't be done for private profit," Labor's immigration spokesman says, as the party reveals it would ditch plans to offload Australia's visa processing system to the private sector, potentially worth more than $3 billion to the winning company.

The Prime Minister implements one of the biggest changes to Liberal Party processes in more than 70 years, but also all but ensures the leadership coup that earned him the nation's top job will be tough to repeat.
